No, no. ntp gets the data from all the servers. It then looks at the times it gets from each server, and groups them into "classes" according to its estimate of the max time error from the server-- ie whether the error intervals overlap or not. It then looks for the largest group of servers all of whose error intervals overlap and uses the average of those times as the time to send on the the ntp engine. The others are "false tickers". It estimates the error by looking at the round trip time and the other machine's estimate of its own max error. > > Thanks, > Nils Brubaker _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
